RECORD OR ACCOUNT FILE.

SPECIFICATION forming part of Letters Patent No. 782,164, dated February'7, 1905,

Application filed June 16,1902. Serial No. 111,807,

To rif/Z 'wh/0m, it nbr/y concern:

Be it known that I, FRANK O. MoELRoY, a citizen ot' the United States,residing at Oolumbus, in the county of Franklin and State ot' Ohio, haveinvented a certain new and useful Improvement in Record or AccountFiles, ot' which the `following is a specification.

My invention relates to the improvement of oiiice-tiles of that class inwhich sheets eontaining accounts or records of various characters aredesigned to be detachably bound between two rigid cover plates or backs;and the objects of my invention are to provide an improved tile andindex of this character so arranged and constructed as to permit ot' thebinding' between the saine back or cover plates two separated sets ofbills or records which have relation to each other and to combinetherewith index-sheets which shall be common to both sets of records oraccounts. These objects I accomplish in the manner illustrated in theaccompanying drawings, in whichi Figure l is a view in perspective ofone of my improved tiles, showing' the same open. Fig. 2v is a rearelevation ot' the same, and Fig. 3 is an end view.

Similar numerals refer to similar parts throughout the several views.

in carrying out my invention I employ the usual back or cover plates land 2, the rear portions ot' which are adjustably connected in thewell-known manner by locking pins or bolts 3, there being in the presentinstance one pair of these locking-pins arranged on each side of thecenter of the upper or outer back or cover plate l. As is common in thisclass otA tiles, the lower ends of the pins are secured in connectionwiththe rear portion of the lower cover-plate 2, while the upperportions ot' said pins pass loosely through openings in the rear portionoil the upper coverplate l and are adapted to be locked in connectionwith said upper cover-plate by a suitable locking device. (Not hereinshown.) Each pair of the pins 3 passes through the rear portions ot' thesheets, forming' one set of reci l l ords, the two sets of record-sheetsbeing' indicated at 4; and in the drawings. 'lheserecord or accountsheets i and 5 are arranged on opposite sides ot' the center ot' theheight of the covers, with a central space, such as that indicated at 6,existing' between the same. At intervals, however, l cause to be boundbetween corresponding leaves or sheets of both sets index-sheets 7, thelatter being' otl such length or height as to extend across the space (5and between the leaves or sheets of both sets. Each ot' theseindex-sheets is preferably provided with an outwardlyprojecting indeX-letter-containing tab, such as is indicated atS.

The advantages ot' the construction described will be apparent when itis understood that the sheets of one set, such as those indicated at 5,are intended for the purpose ot' keeping' thereon accounts ot' billswhich have been paid, each sheet bearing the account oi' a singlecustomer, while the sheets of the remaining set likewise contain theaccounts ot' customers which are unpaid. rhen one of these latteraccounts is paid, the sheet containing' the same is removed from itsplace in the unpaid account-sheets and inserted between the properindex-pages ot the paid set. This system admits of the keeping' oi' acomplete iile for any given term ot' paid and unpaid accounts, whichgreatly facilitates the examination of either class oi' such accountsand admits of the ready insertion ot new accounts under the properindex-heading as these accounts occur.

Having now fully described my invention, what l claim, and desire tosecure by Letters Patent, is

l. Ina device ot' the characterdescribed, the combination withcover-plates and binding means for adjustably connecting the same, ot'index-sheets, and detachable subindex-leaves arranged in separated set-son opposite sides ot' the center ot' each index-sheet.

2. ln a device of the character described, the combination withcover-plates and binding' means for adjust-ably connecting the rearportions thereo t, ot' separated sets ot' paper leaves detacbably heldbetween said cover-plates, and with all the posts and sets of opposedsubinindex-sheets common to the sets arranged at dex-leaves, the leavesof eacb set detacliably bridging the space between the sets.

5 3. In a device of the character described, the combination with thecover-plates and the four binding-posts, of index-sheets engaged FRANKC. MCELROY.

intervals between the leaves of said sets and engaging two of the posts.
